On the twenty-eighth of June, 1914, the Archduke Francis Ferdinand, heir to the Austrian throne, was murdered by a Serb in Serajevo, the capital of Bosnia. The murder was the most momentous crime ever committed in the world, for it altered the geography and the political and social history of that planet, and changed the entire face of the civilized and uncivilized globe. Generations unborn were to feel the consequences of that murder.
